Timing chain fault precursor
The precursors of timing chain failure include: abnormal noise of the engine, weak starting, increased fuel consumption, increased oil consumption, serious exhaust emission pollution, slow acceleration response, yellow fault light of the engine, insufficient power and many other problems
How should the timing chain be checked 1 Check the elongation of the chain at three or more places with a spring scale. If it exceeds the service length, it should be replaced in time. 2. Use a vernier caliper to detect the wear degree of the automobile camshaft and crankshaft sprocket. If it exceeds the service limit, it should be replaced in time. 3 Use vernier caliper to monitor the thickness of zipper and chain shock absorber. If it exceeds the service limit, it should be replaced in time 4 Check the elongation, wear and fracture of the timing chain. If there is slight damage, it can not be used anymore. Although the functions of the timing belt and the timing chain are the same, their working principles are still different. Compared with the timing chain, the structure of the timing belt is relatively simple, there is no need for lubrication in the working state, and the working state is relatively quiet, The installation and maintenance are convenient, but the timing belt is a rubber component, which will be worn and aged after long-term use. Regular observation and maintenance are required. Once it is broken, the engine will be disordered, resulting in damage to parts and components.
